Which Eretz Yisrael? The Higher Eretz Yisrael
“You shall dwell on the land securely” this is the refinement of the physical material.
“And you shall dwell securely on your land” which means that the physical material will return to its spiritual state and “the earth will be filled with the knowledge of G.d”.
If so, there are hints in parashat Behar on the holiness of the land, which is the physical material…and the Land of Israel which G.d wants hints at the Higher Land (Eretz Elyona) which is all of Israel, as it says “your people are all tzaddikim, they will dwell on the land forever”.
